Step 1: Confirm WSUS 3.0 SP2 installation requirements

Before you install or upgrade to Windows Server Upgrade Services 3.0 Service Pack 2 (WSUS 3.0 SP2), confirm that both the server and the client computers meet the minimum system requirements and confirm that you have the necessary permissions to complete the installation.

Confirm that the server meets the minimum system requirements for hardware, operating system, and other required software. Detailed system requirements are listed in the WSUS 3.0 SP2 System Requirements section of the WSUS 3.0 SP2 Deployment Guide. If you are using Server Manager to install the WSUS 3.0 SP2 Server, you can confirm that you meet the software requirements by following the steps in the Preparing to install WSUS 3.0 SP2 section.

If you install roles or software updates that require you to restart the server when installation is complete, then restart the server before you install WSUS 3.0 SP2.

Automatic Updates is the client of WSUS 3.0 SP2. Automatic Updates has no hardware requirements other than being connected to the network.

Confirm that computer on which you are installing Automatic Updates meets the WSUS 3.0 SP2 system requirements for Client computers. Detailed system requirements are listed in the WSUS 3.0 SP2 System Requirements section of the WSUS 3.0 SP2 Deployment Guide.

If you install software updates that require you to restart the computer, restart it before you install WSUS 3.0 SP2.

Log on to the server on which you plan to install WSUS 3.0 SP2 by using an account that is a member of the Local Administrators group.

Click Start, point to Administrative Tools, and then click Server Manager.

In the right side pane of the Server Manager window, in the Roles Summary section, click Add Roles.

If the Before You Begin page appears, click Next.

On the Select Server Roles page, confirm that Application Server and Web Server (IIS) are selected. If they have been selected, use the remainder of this step to confirm that the required role services are selected. Otherwise, install Application Server and Web Server (IIS) as follows.
